GARBAGE-PRESS.

Specification of Letters Patent. P tented Mar. 15, 1910.

Application filed March 10, 1909. Serial Nos 182,509.

To all whom it may concern:

Belt known that I, Pnncy B. TAYLon, a citize'iroi" the United States, and a. resident. of 800 Broad street, Ner'ark', county of Essex, and State of New Jersey, have invented certain now and useful Improvements in Garbage-Presses, fully described and represented in the following specification and the accompanying. drawings, forming a part of the same.

This invention relates to that class of garbage presses in which an upright cylinder containing a piston is used to compress the material and the cylinder has a permeable lining through which the liquid is discharged during the pressing operation. Such lining forms an annular chamber around the pressing chamber, and has an outlet with a cock at its bottom, and the in vention consists in providing a ring in such annular chamber to divide the same near its lower end, and in the use of a hinged door applied to the entire bottom of the pressing chamber with a tight hopper beneath such door into which it can be droppedto dis charge the entire contents of the press simultaneously to a conveyer for transporting them to a drier or other destination. A system showing this combination is illustrated in my application No. 482,508, filed March 10, 1909, with title Sealed system for garbage disposal.

The present invention will be understood by reference to the annexed drawing, in which Figure 1 is a side elevation of the press with connections extended therefrom torreceiving the garbage and delivering it by airtight connections; Fig. 2 is a cross section on line 2-2 in Fig. 1.; and Fig. 3 is a vertical section where hatched, in the plane of Fig. 1.

The press comprises a cylindrical chamber 1 having a chute connected with one side near the toplor admitting the garbage, and

provided with a tight cover 3, and a, hinged uoor t at the bottom. The shell 5 of the press is lined with vertical sta (l with intcrspares (3 through which the liquid maybe expressed, the stares being held at a little distance from the casii'ig by spacing-rings 7 to form an annular chan'iber 8 for the reception of the expressed liquids. A pipe and cock 9 serve to drain this chamber at. the bottom.

The pressing is effected by a perforated piston-plate 10 which may operate merely by its own weight, as shownin Fig. 3, in which case it is provided with a rod ll'extended through a stuffing-box 12 upon the cover, and connected with a chain 13 or other suit able means for raising it and holding it raised when required. The chute 2 is connected with the side of the casing so that thepiston 'may be raised above the inlet. of the chute to permit the material to enter below the piston. This arrangement avoids the removal of the cover and the piston to insert a charge in the press, and thus avoids any escape of vapors from the press during the charging of the chamber 1.

It preferred, the piston may be depressed by force, as shown in Fig. 1, by a screw 14 connected with the top of the rod by a coupling 15 and driven by gearingupon a rotary nut 16 mounted in a bearing l7 above the top of the cover. The cover is provided with a steam-inlet-pipe 18 having a cook 19, and with a gas-outlet-pipe 20 having a cock 21. A. ring 22 divides the chamber 8 near its lower end and an outlet-pipe with a cock 9: is applied to the chamber just above the ring. 7

A hop or 23 is shown connected to the bottom or the press of sufficient size to drop the door 4 to discharge the solid material at the close of the pressingoperation, and a conveyer 21 is shown inclosed in a tight casing 25 which may be connectedjwith a tightly inclosed drier or any agency in which the material may be treatedwithout expo-' sure to the atmosphere, or by which it may be conducted to a furnace for consumption under a boiler. The door is shown in dotted lines in its lower position when 0 18B. It will be observed that the door when ropped opens the entire bottom of the pressing chamber so as to discharge the entire contents of the press simultaneously to the hopper, from which it is delivered by the conveyer. This class of door supports the material more .firmly than anyother, and thus permits any desired pressure whether of steam or of weight to be exerted upon the material in the press.

In Fig. 3, the lower end of an ordinary digrster 26 is shown, having its outlet connected wit-h the chute 2 upon the shell of the press, and'such outlet provided with a gate 27 which may be tightly-closed while the press is in operation. 'The closing of manner 1 such gate and the door 4 at the bottom of the piston is lowered, and this brings much of the fluid constituents to the surface from which they runoff between the staves into the chamber 8. The valve 9 is then opened and the liquid is run elf to a settling tank or other suitable tight receptacle. After all the free liquid has run off, the piston is allowed to descend and rest upon the remaining mass, and steam of aboutGO lbs. pressure is introduced by the valve 19 which not only forces the piston down hard upon the mass and thus helps to press it, but also passes through the perforations in the iston and into the mass of garba e, whicli it penetrates because of the out et afforded by the bottom -valve 9. The pressure and action of the steam operates to force the remaining rease into the chamber 8 below the ring 22, rom which it drains to the settling-tanks or other receptacle through the valve 9. The piston during this operation prevents v the boiling up of the mass, at the same time allowing steam to pass through the perforations and through the mass under treatment, which is the most effective means of extractin the grease. After the mass has been s'u jected to the steam for a suitable time, the steam is cut off by closing the valve 19, the piston is raised to the top of the ress, and the door 4 is opened and the resi ue of the material is dropped into the conveyer j2 l'whieh delivers it throu h its tight casmg 25' to any desired point. uring the pressing operation, the cook 21 for the escape of as is kept closed to maintain pressure within the press; but at suitable times this gas-cock is opened to permit the vapors and gases to-escape to a suitable receptacle, as a condensing-tank, where the vapors may be condensed and from which the gas may be led to the furnaceof a boiler to be disposed of by combustion.

The operation with the screw 14, shown in Fig. 1, would be the same as just described,

- exce t that the movement of the. piston won d be graduated to correspond with the escape of the liquid from the material, so as to descend in the same'degre'e that the material shrank through the removal 'ofthe liquid. With the screw, more of the liquid maybe expressed and the residue discharged from the press in a'somewhat drier condition.

From the above' description it will be readily understood that the material is placed in the press and operated upon, and the liquid and solid ingredients effectually separated and delivered from the press without any exposure to the atmosphere.

vThe constructive features of the press may be altered, and its connection for receiving and discl'larging the material may be varied without departing from the invention, the essential features of which are the perfo rated piston and the casing lined with staves and having a chamber outside the same from which the liquid may be drawn.

Although this press was devised particu-- larly for the pressingof garbage, it'may be used for any other purpose in which a press is desired from which volatile oroifensive vapors cannot escape during the pressing annular chamber 8 around the staves, means for drawing oil the expressed liquid from such chamber, a chute liavinginlet upon the side of the casing nearthe top with a gate to close such inlet, a downwardly swinging door at the bottom of the casing for dischargin the pressed material,the hopper 23 extendc from the bottom of the casing inclosing the door and a piston with means for rinsing it above-the inlet of the chute.

2. The.garbage press, consisting of the casing 5 having the lining of states 6 with annular chamber 8 around the staves, a pipe and cock for drawing off the expressed liquid from the bottom of; the chamber, a ring dividing the chamber horizontally above such pipe, a pipe and cook connected with the chamber above such ring, a chute havin inlet upon the side of the casing near the top with a gate-to close such inlet, a'tight door at the bottom of the casing for discharging the pressed material, and a piston with. means for raising it above the inlet of the chute.

BQThe garbage press consisting of the casing -5 havinga tight cover on top provided with the steam-inlet-pipe 18 and the stufiing-box 12 and havingalining of staves 6 with annular chamber 8 around the stares, a pipe and cook for drawing off the expressed liquid from the bottom of the annular chamber, a ring dividing the chamber horizontally above such pipe. with a pipe and cock connected to such chamber above the said ring, a chute for supptying the material to the casing near the top, a downwardly swinging door at the bottom of the casing fordischarging the pressed material, the hopper 23 extended from the bottom of the casing, inclosing the door, and a piston set forth.

inlet-pipe l8 and having a lining of staves (3 with'annular chamber 8 around the same and the outlet-pipe 9. for drawing off the expressed liquid from the bottom of the chamber, a downwardly swinging door at theg'bpttom of the casing for" discharging the pressed material, the hopper 23 extended from the bottom of the casing and inclosing go the said door, and a piston. having numerous perforations and a rod fitted to the stuffingbox, the steam supplied by the pipe 18 op erating through the perforations in the piston to cook the material underneath the same and to force the liquid therefrom to,

the outlet-pipe 9.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
